The true Southern watermelon is a boon apart, and not to be mentioned with
commoner things. It is chief of the world's luxuries, king by the grace of God
over all the fruits of the earth. When one has tasted it, he knows what the
angels eat. It was not a Southern watermelon that Eve took; we know it because
she repented.
